RIDING AND OPERATING ATTACHMENT FOR HARROWS.

SPECIFICATION forming part of Letters Patent No. 771,466, dated. October4, 1904.

Application filed April 27, 1904. Serial No. 205,179. (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. DOBBERPUHL, J r., acitizen of the UnitedStates, residing at Groton, in the county of Brown and State of SouthDakota, have invented certain new and construction of parts, thepreferred form whereof will be hereinafter clearly set forth, andpointed out in the claim.

The prime object of my invention. among others, is to provide areliably-efficient riding attachment for harrows which will be entirelysafe both for the operator and for the draft- "animals, by which theharrow or harrow-sections, as the case may be, will be placed under thecomplete control of the operator.

A further object of my invention is to provide a set of carrying-wheelsdesigned, primarily, for carrying the attendant or driver and which alsoserves as a controlling means for the barrow or harrow-sections placedin cooperation therewith.

Other objects and advantages will be hereinafter made clearly apparent,reference being had to the accompanying drawings, which are made a partof this application,and in which- Figure 1 shows a top plan view of myinvention complete ready for use. Fig. 2 is a central section of Fig. 1,showing the position of one of the levers by dotted lines. Fig. 3 showsa perspective view of one of the harrow-sections removed and ready tohave a plurality of teeth located therein in the usual manner. Fig. 4 isa transverse section on a line with the main or carrying axle.

In order to conveniently refer to the various details and cooperatingaccessories, numerals will be employed, the same numeral applying to asimilar part throughout the several views.

It will be understood that any preferred construction and any desiredmaterial may be adopted, the construction and arrangement of partsherein illustrated being but one of many possible ways myinvention canbe carried out or applied to practice, and I therefore do not wish to beconfined strictly to the exact presentation herein disclosed.

Referring to the numerals on the drawings, 1 designates the main orcarrying axle,which may be made in the manner illustrated of a solidpiece of material or may be made tubular, as from a section of piping ofsuitable size. Upon the ends of the axle I rotatably secure thecarrying-wheels 2. In the present instance I have illustrated threeharrow-sections, which are designated by the numerals 8, i, and 5; butit will be understood that any desired number of harrow-sections may beused, according to the needs of the operator.

Near each end of the axle 1 I secure the clips or eyebolts 6, andpivotally secured to said clips are the forwardly-extending bars 7, theends of which are rigidly attached to the ends of the cross-bar 8, whichlatter is provided at its central part with a staple-like member 9,adapted to be connected to the hook member 10, the upper end of the hookmember being attached to the eyebolt 11, passing through the tongue 12,as clearly shown in Figs. 1 and 2. The rear end of the tongue ispivotally connected -to the central portion of the axle, as designatedby the numeral 13; but the draft-animals are connected to the cross-bar8 by means of the chain or plurality of link members 1 1, it beingunderstood that a suitable doubletree or evener 15 is provided in theusual manner, each end whereof is provided with swingletrees 16 forconnection with the trace-chains of the harness. The harrow-sections 3,4. and 5 are each provided with apair of clevises 17,whereby they may beplaced in pivotal connection with the eyebolts 18 by means of thelap-rings 19 or equivalent devices. It will thus be observed that thedraft-animals are attached directly to the harrow-sections and notindirectly, as is common when the doubletree is attached to thedraft-tongue, a most valuable and important desideratum.

In order to place the plurality of harrowsections under the completecontrol of the operator, who will occupy the seat 20, I suspend each ofthe l1arrow-sections and provide for each section a controlling-lever,said controlling-lever being designated by the numeral 21, there beingone lever for each harrowsection.

lt will be observed by reference to Fig. 2 and other views that the seat20 is mounted upon the standard 22, which latter is carried by therearwardly-extending platform 23, the forward end of the platform beingrigidly connected to the central portion of the axle and may be providedwith a foot-guard 2 1 or equivalent device, whereby the operator will bemore securely located in the seat 20, as will be obvious.

The rear end of the platform 23 is provided with an aperture designed toreceive the upwardly-directed stem or finger 25, saidlinger forming anintegral extension of the swiveled member 26, which latter is bifurcatedat its rear end, thereby providing the branches or arms 27, betweenwhich I rotatably mount the auxiliary carrying-wheel 28, and inasmuch assaid wheel 28 is thus left to move freely to either the right or left areliable means is thus provided at a simple cost of material and laborfor holding the platform 23 and its accompanying seat in properposition.

By reference to Fig. 1 it will be observed that each of the levers 21 isprovided with the lateral extension 29, held in place by the eyebolts orstaples 30 or equivalent means, said branch or lateral extension 29 alsohaving the forwardly-projecting crank-arm 31, the end of which ispivotally connected to the carrying-chain 32, which extends down to thecentral portion of one of the harrow-sections, and it is thereforeobvious that when the levers 21 are drawn backward the harrow-sectionsWill be lifted, thus enabling the barrow to be readily transportedwithout injury to the teeth, as upon a roadway or from field to field.Inasmuch as any one of the harrow-sections may thus be readily elevated,it is obvious that the entire machine may be drawn over a protrudingstone or a small stump, root, or the like, leaving the otherharrow-sections free for the performance of their ofiice of pulverizingthe surface of the ground.

It will be observed that in the present instance 1 have shown aplurality of pointed teeth 33; but it is obvious that any form of teethmay be employed and any desired variety of barrow-sections adopted, myobject being to place all of the barrow-sections, whether one or anumber of them are employed, under the complete control of the driver.

By reference to Fig. 2 it will be understood that theforwardly-projecting crank-arm 31 is curved a portion of its length,whereby it will fit around under the main axle 1, though any preferredformation or construction of said crank may be adopted. It willfurthermore be observed that I have provided for the tongue 12 a pair ofbracing members or laterally and rearwardly extending arms 34, theforward ends being bolted to the sides of the tongue, as indicated bythe numeral 35, while the rear ends are pivotally connected to theeyebolts 36 or equivalent means.

Various changes and modifications in the construction may be madewithout departing from the spirit or scope of my invention, and

believing that the construction and manner of using my improved ridingand barrow-carrying appliance have thus been made clearly apparentfurther description 1s deemed unnecessary.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The herein-described combined riding and barrow-carrying appliance,comprising a carrying-axle 1 having suitable carrying-wheels rotatablymounted thereon; a rearwardly-extending platform rigidly secured to saidcarrying-axle; an auxiliary carrying-wheel swiveled in the rear end ofsaid platform; a plurality of barrow-sections; a crossbar 8 hav ingrearwardly-extending arms 7 pivotally connected to said carrying-axle;means to pivotally connect the harrow -sections to said cross-bar andadditional means to connect the draft-animals to said bar; aguiding-tongue pivotally secured to said carrying-axle and bracedagainst lateral movement; a carryingseat' for the operator and acontrolling-lever for each barrow-section whereby when the levers areoperated one or all of the barrow-sections will be elevated or depressedas desired, all combined substantially as specified and for the purposeset forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
